CHARLES s. AMES, OE BISHOP, ILLINOIS.

CHANNELINGMACHINE.

SPECIFICATION' forming part of Letters Patent No. 345,873, dated July 20, 1886.

Application filed January 8, 1886.

To all whom it may concern:

Beit known that I, CHARLES S. AMES, of Bishop, in the county of Mason and State of Illinois, have invented a new and Improved Channeling-Machine, of which the following is a full, clear, and exact description.

My present invention relates to the construction of a channeling-machine applicable for use in connection with a leather-rolling machine, as is illustrated and described in my application No. 175,922, liled on the 2d day of September, 1885; and the invention consists of a pair of adjustably-mounted channelingblades so arranged that they may be mounted in front of the formers of a leather-rolling machine, such as the one just referred to.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a view of the leather-rolling maing attachment, the view being taken in vertical cross-section. Fig. 2 is a longitudinal sectional View ofthe channeling-machine; and Fig. 3 is av plan view of said machine, one of the guiding-plates being removed to disclose the construction of the parts.

Referring, now, to the general construction illustrated in Fig. 1 A represents the grooved wheel, and B the former, of a leather-rolling machi'ne, the shafts which carry the two parts named being mounted in bearings carried by standards C.

The channeling-machine which forms the subject-matter of this application is mounted On a cross-bar, D, which is supported by arms E, that are bolted to the standards C. In the bar D there is a central slot, a, upon either side of which there is formed a groove or way, b, and in these grooves there are mounted two supporting-irons, F F', whieh.carry channeling-knives G G', that are secured to the supporting-irons by set-screws c c', the knives G being formed with central longitudinal slots, d, so that they Inay be adjusted to regulate the depth of cut. Above the irOnsF there are arranged guiding-plates H H', formed with shoulders It h, the point of the knives, however, being held against displacement by apertured plates I I', through which the knives project, the plates named being apertured to receive the bolts N, which pass through said parts and through slot c of the bar D, to engagey with winged nuts a, by which they are Serial No. 187,994. (No model.)

bound to the bar D. Such being the general construction of the device, it will readily be understood that by loosening the winged nuts n the knives may be adj usted to operate upon any width of strap, and it will also be understood that the depth of cut can be regulated by raising or lowering the knives, this movement being brought about by loosening the set-screws c. The devices having been properly adjusted, the strap is fed in between the knives, being guided bythe shoulders It h of the plates H H', the leading end of the strap being carried into the bite of the rollers A and the disk or former B, which, in rotation of the shaft upon which the roller A is mounted, will carry the strap forward and the required channel will be formed along the edges of the strap.

By the use of such a machine as has been described there is a great saving of time, labor, and expense in channeling leather, and

although I have illustrated the invention in connection with a leather-rolling machine, it will of course be understood that the device might be used with any other form of rollers which would bite upon the strap and carry it forward, or the machine might be used without any rollers, in which case the strap would be simply pulled by hand or otherwise over the edges of the knives G G'.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a channeling-machine, the combination, with the bar D, of supporting-irons carrying channeling-knives, guiding-plates, and an attaching device, all arranged to operate substantially as described.

2. In a channeling-machine, the combination, with a bar, D, of supporting-irons F F', adj ustably connected to said bar-and carrying knives G G', and guide-plates H H', formed with shoulders h It, substantially as described.

3. In a channeling-machine, the combination, with a bar, D, formed with a central slot, a, and ways b I), of supporting-irons F F', channeling-knives G G', formed with a slot, d, and held in place by set-screw c, knife-guiding plates I I', guiding-plates H H', formed with shoulders h h, bolts N, and nuts n, substantially as described. i
